[kamailio/kamailio] siptrace: siptrace: fix memory leak in fake replies tracing (#2295)

by Federico Cabiddu

#### Pre-Submission Checklist    - [X] Commit message has the format required by CONTRIBUTING guide - [X] Commits are split per component (core, individual modules, libs, utils, ...) - [X] Each component has a single commit (if not, squash them into one commit) - [X] No commits to README files for modules (changes must be done to docbook files in `doc/` subfolder, the README file is autogenerated) #### Type Of Change - [X] Small bug fix (non-breaking change which fixes an issue) - [ ] New feature (non-breaking change which adds new functionality) - [ ] Breaking change (fix or feature that would change existing functionality) #### Checklist:  - [X] PR should be backported to stable branches - [ ] Tested changes locally - [ ] Related to issue #XXXX (replace XXXX with an open issue number) #### Description  When tracing a faked reply (like 200 for CANCEL), the sip msg used to retrieve the tracing parameters is the transaction's uas one (uas.request) which might have the from header parsed or not, depending on the routing script actions (by default, if I'm not wrong, it is not parsed). If the header is not parsed, calling get_from in trace_onreply_out function will lead to a memory leak, beacause the header is parsed in pkg memory not freed when the transaction is deleted.

[kamailio/kamailio] async_http_client crash (#2286)

by Alex Balashov

Version: 5.3.3 `065668` Platform: CentOS 7 (3.10.0-862.14.4.el7.x86_64) I seem to have a persistent intermittent crash on all five gateways which use `http_async_client` to query an HTTP API. In all cases, the crash is on attempt to access or reference an AVP called `$avp(is_subscribe)`: ``` Program terminated with signal 11, Segmentation fault. #0 0x00000000005d479b in match_by_name (avp=0xabcdefed, id=45, name=0x7fff9379c668) at core/usr_avp.c:378 378 if (id==avp->id && avp->flags&AVP_NAME_STR && hMissing separate debuginfos, use: debuginfo-install libuuid-2.23.2-52.el7_5.1.x86_64 nss-pem-1.0.3-4.el7.x86_64 (gdb) where #0 0x00000000005d479b in match_by_name (avp=0xabcdefed, id=45, name=0x7fff9379c668) at core/usr_avp.c:378 #1 0x00000000005d54bf in search_next_avp (s=0x7fff9379c660, val=0x7fff9379c630) at core/usr_avp.c:499 #2 0x00000000005d4f04 in search_avp (ident=..., val=0x7fff9379c630, state=0x7fff9379c660) at core/usr_avp.c:465 #3 0x00000000005d4913 in search_first_avp (flags=1, name=..., val=0x7fff9379c630, s=0x7fff9379c660) at core/usr_avp.c:414 #4 0x00007f3f6ba529fd in ops_is_avp_set (msg=0xb04f60 <_faked_msg>, ap=0x7f3f73296ed8) at avpops_impl.c:1821 #5 0x00007f3f6ba60d47 in w_is_avp_set (msg=0xb04f60 <_faked_msg>, param=0x7f3f73296ed8 "", op=0x0) at avpops.c:1059 #6 0x0000000000480f3d in do_action (h=0x7fff9379ce70, a=0x7f3f732a8b30, msg=0xb04f60 <_faked_msg>) at core/action.c:1077 #7 0x000000000048da7c in run_actions (h=0x7fff9379ce70, a=0x7f3f732a8b30, msg=0xb04f60 <_faked_msg>) at core/action.c:1576 #8 0x000000000048e13d in run_actions_safe (h=0x7fff9379dae0, a=0x7f3f732a8b30, msg=0xb04f60 <_faked_msg>) at core/action.c:1640 #9 0x0000000000438ff3 in rval_get_int (h=0x7fff9379dae0, msg=0xb04f60 <_faked_msg>, i=0x7fff9379d318, rv=0x7f3f732a8d70, cache=0x0) at core/rvalue.c:915 #10 0x000000000043d5a3 in rval_expr_eval_int (h=0x7fff9379dae0, msg=0xb04f60 <_faked_msg>, res=0x7fff9379d318, rve=0x7f3f732a8d68) at core/rvalue.c:1913 #11 0x000000000043d9f6 in rval_expr_eval_int (h=0x7fff9379dae0, msg=0xb04f60 <_faked_msg>, res=0x7fff9379d7cc, rve=0x7f3f732a9598) at core/rvalue.c:1921 #12 0x000000000048097b in do_action (h=0x7fff9379dae0, a=0x7f3f732aa9c0, msg=0xb04f60 <_faked_msg>) at core/action.c:1047 #13 0x000000000048da7c in run_actions (h=0x7fff9379dae0, a=0x7f3f732aa9c0, msg=0xb04f60 <_faked_msg>) at core/action.c:1576 #14 0x000000000048e205 in run_top_route (a=0x7f3f732aa9c0, msg=0xb04f60 <_faked_msg>, c=0x0) at core/action.c:1661 #15 0x00007f3f705f7d0e in async_http_cb (reply=0x7f3f2b7ee620, param=0x7f3f2b7eca18) at async_http.c:256 #16 0x00007f3f705f0dab in check_multi_info (g=0x7f3f2abeb9e8) at http_multi.c:597 #17 0x00007f3f705e84ec in event_cb (fd=6, kind=2, userp=0x1d7cdf0) at http_multi.c:145 #18 0x00007f3f70131a14 in event_process_active_single_queue (activeq=0x1c6f820, base=0x1d3ad90) at event.c:1350 #19 event_process_active (base=<optimized out>) at event.c:1420 #20 event_base_loop (base=0x1d3ad90, flags=0) at event.c:1621 #21 0x00007f3f705f490f in async_http_run_worker (worker=0x7f3f2abd1bb0) at async_http.c:92 #22 0x00007f3f705dcb17 in child_init (rank=0) at http_async_client_mod.c:366 #23 0x000000000057a810 in init_mod_child (m=0x7f3f73245168, rank=0) at core/sr_module.c:780 #24 0x000000000057a4ac in init_mod_child (m=0x7f3f73245d58, rank=0) at core/sr_module.c:776 #25 0x000000000057a4ac in init_mod_child (m=0x7f3f73246340, rank=0) at core/sr_module.c:776 #26 0x000000000057a4ac in init_mod_child (m=0x7f3f732467f8, rank=0) at core/sr_module.c:776 #27 0x000000000057a4ac in init_mod_child (m=0x7f3f73246e38, rank=0) at core/sr_module.c:776 #28 0x000000000057a4ac in init_mod_child (m=0x7f3f73247210, rank=0) at core/sr_module.c:776 #29 0x000000000057a4ac in init_mod_child (m=0x7f3f73247978, rank=0) at core/sr_module.c:776 #30 0x000000000057a4ac in init_mod_child (m=0x7f3f73247da0, rank=0) at core/sr_module.c:776 #31 0x000000000057af5a in init_child (rank=0) at core/sr_module.c:825 #32 0x0000000000426bc1 in main_loop () at main.c:1753 #33 0x000000000042e63a in main (argc=13, argv=0x7fff9379edb8) at main.c:2802 ``` Most recently, it is here: ``` route { $avp(is_subscribe) = 0; ... $http_req(method) = 'GET'; $http_req(suspend) = 1; $http_req(hdr) = "x-api-key: " + $sel(cfg_get.api.whitelist_key); t_newtran(); http_async_query("https://some_host/check_ip_in_whi telist?ip=$(si{s.escape.common})", "WHITELIST_CHECK"); } ... route[WHITELIST_CHECK] { if(!is_avp_set("$avp(is_subscribe)")) { xlog("L_INFO", "[R-HTTP-REPLY:$ci] !> AVP is_subscribe is undefined -- cannot process further\n"); sl_send_reply("500", "Internal Server Error"); exit; } ``` However, adding `is_avp_set()` was my attempt to put a safe-guard around unsafe access of this AVP. It didn't work: ``` (gdb) print *name $1 = {s = 0x7f3f73261835 "is_subscribe)", len = 12} (gdb) print avp $2 = (avp_t *) 0xabcdefed (gdb) print avp->id Cannot access memory at address 0xabcdefed ``` Note that I am making the assumption above that AVPs created in the main request route will be available in the `http_async_client` callback, because it is just a suspended TM transaction underneath -- right? So, transaction-persistent variables such as AVP should be visible throughout the lifetime of the transaction just as for a conventional async TM transaction, I would think. Digging further into the mesage being handled in `async_http_cb()`, it is always a normal HTTP `200 OK` reply: ``` (gdb) set print elements 0 (gdb) frame 15 #15 0x00007f3f705f7d0e in async_http_cb (reply=0x7f3f2b7ee620, param=0x7f3f2b7eca18) at async_http.c:256 256 if (run_top_route(act, fmsg, 0)<0) { (gdb) print *reply $5 = {retcode = 200, result = 0x7f3f2b7ec560, error = '\000' <repeats 255 times>} (gdb) print *(reply->result) $6 = { s = 0x7f3f2b7ee798 "HTTP/1.1 200 OK\r\nContent-Type: application/json\r\nContent-Length: 16\r\nConnection: keep-alive\r\nDate: Wed, 15 Apr 2020 15:06:52 GMT\r\nx-amzn-RequestId: d3a44941-e0c4-4cb9-9144-ea54d929c300\r\nx-amz-apigw-id: LCJqBF7CIAMFXCw=\r\nX-Amzn-Trace-Id: Root=1-5e97230c-4fe1af7d072275d95c231a4c;Sampled=0\r\nX-Cache: Miss from cloudfront\r\nHia: 1.1 ade18dc841d2e1cc8ef49611c5d4c93e.cloudfront.net (CloudFront)\r\nX-Amz-Cf-Pop: IAD89-C2\r\nX-Amz-Cf-Id: 3s1S2kvOgL7L4ZKMlWwQnfIxHmWFGz0PHbcNFefYA1tZ1j0AGy3JHg==\r\n\r\n{\"status\":false}\300\300\300\300", len = 504} ``` Any insights would be appreciated! These crashes are happening basically hourly from nowhere, after over a year of undisturbed operation. -- You are receiving this because you are subscribed to this thread.
